Troubled Waters iii Executive Summary

ctober 18, 2007 marks the 35th anniversary of the Clean Water Act, a landmark law intended to restore Oand maintain the physical, chemical and biological integrity of the nation’s waters. In passing the Clean Water Act, Congress set the goals of eliminating the discharge of pollutants into the nation’s waterways by 1985 and making all U.S. waterways fishable and swimmable by 1983. Although we have made significant progress in improving water quality since the passage of the Clean Water Act, we are far from realizing the Act’s original vision.

Using information provided by the U.S. Environmental Protection Agency (EPA) in response to a Freedom of Information Act request, this report analyzes all major facilitiesa that exceeded their Clean Water Act permits between January 1, 2005 and December 31, 2005; reveals the type of pollutants they are discharging into our waterways; and details the extent to which these facilities are exceeding their permit levels.

More than two decades after the drafters of the 1972 Clean Water Act intended for the discharge of all pollutants to be eliminated, facilities across the country continue to violate pollution limits, at times egregiously.

Findings include:

Thousands of facilities continue to exceed their Clean Water Act permits.

Nationally, more than 3600 major facilities (57%) exceeded their Clean Water Act permit limits at least once between January 1, 2005 and December 31, 2005.

The 10 U.S. states with the highest percentage of major facilities exceeding their Clean Water Act permit limits at least once are Maine, Massachusetts, Rhode Island, New Hampshire, Ohio, Connecticut, New York, North Dakota, California, and West Virginia.

The 10 U.S. counties with the most facilities exceeding their Clean Water Act permits at least once in this period are Harris County, Texas; Los Angeles County, California; Worcester County, Massachusetts; New Haven County, Connecticut; Calcasieu Parish, Louisiana; Allegheny County, Pennsylvania; Hartford County, Connecticut; Will County, Illinois; Wayne County, Michigan; and Erie County, New York.

These facilities often exceed their permits more than once and for more than one pollutant.

The 3600 major facilities exceeding their permits in the time period studied reported more than 24,400 exceedances of their Clean Water Act permit limits. This means that many facilities exceeded their permits more than once and for more than one pollutant.

a Facilities are designated as “major” based on an EPA scoring system that considers a combination of factors, including toxic pollutant potential, streamflow volume, public health impacts, and proximity to coastal waters.

Troubled Waters 1 The 10 U.S. states with the most exceedances of Clean Water Act permit limits between January 1, 2005 and December 31, 2005 are Ohio, Pennsylvania, New York, Texas, California, Massachusetts, Louisiana, Tennessee, Alabama, and Florida.

Nationally, 628 major facilities exceeded their Clean Water Act permit limits for at least half of the monthly reporting periods between January 1, 2005 and December 31, 2005.

These facilities often exceed their permits egregiously.

Major facilities exceeding their Clean Water Act permits, on average, exceeded their permit limits by 263%, or nearly four times the allowed amount.

The 10 U.S. states with the highest average permit exceedance between January 1, 2005 and December 31, 2005 are New Mexico, Vermont, Arizona, West Virginia, Iowa, Mississippi, Illinois, Indiana, California, and Hawaii.

Nationally, major facilities reported more than 1800 instances between January 1, 2005 and December 31, 2005 in which they exceeded their Clean Water Act permit limits by at least six-fold (500%).

The U.S. states with at least 100 exceedances of at least 500% above the permit limit are California, Pennsylvania, and Ohio.

Our federal leaders should be working with the states to address this illegal pollution and clean up all of our waterways. Over the last six years the Bush administration has suggested, proposed or enacted numerous policies that undermine the Clean Water Act and threaten the future of America’s rivers, lakes, streams, wetlands and oceans. The administration has not only undercut the Clean Water Act, but also eliminated Clean Water Act protections from key waterways altogether.

Rather than weakening the Clean Water Act, the Bush administration and state officials should: restore Clean Water Act protections to all waterways; tighten enforcement of the Clean Water Act; strengthen implementation of the Clean Water Act to better protect our rivers, lakes and streams; and ensure the public’s right to know about water pollution by increasing and improving access to compliance data and discharge reporting.

Introduction: The State of America’s Waters

n 1972, Congress passed the Clean Water Act, creating the nation’s first comprehensive law for I improving the quality of our rivers, lakes and streams. The Clean Water Act marked a distinct change in the direction of water pollution control. The Clean Water Act instituted requirements for water quality-based controls and added an equal emphasis on technology-based, or end-of-pipe, control strategies. The Act set several goals, stating “it is the national goal that the discharge of pollutants into navigable waters be eliminated by 1985”; “it is the national goal that wherever attainable an interim goal of water quality which provides for the protection and propagation of fish, shellfish, and wildlife and provides for recreation in and on the water be achieved by July 1, 1983”; and “it is the national policy that the discharge of toxic pollutants in toxic amounts be prohibited.”1

Thirty-five years later, although the Clean Water Act has helped to clean up the nation’s waterways, we have not yet achieved these goals. Consider the following:

Approximately 39% of our rivers, 46% of our lakes and 51% of our estuaries are impaired for one or more uses and thus still too polluted for safe fishing or swimming.2

The U.S. Environmental Protection Agency (EPA) estimates that more than 20,000 bodies of water throughout the country are too polluted to meet basic water quality standards.3

Across the country, pollution caused more than 25,000 beach closings and advisory days in 2006 at ocean, bay, and Great Lakes surveyed beaches, the highest level in 17 years.4

In 2006, 32 states and the District of Columbia had statewide fish consumption advisories in place because of toxic pollution. Federal or state agencies have issued fish consumption advisories for 38% of the nation’s total lake acres (excluding the Great Lakes), all of the Great Lakes, 26% of total river miles, and nearly 65% of the country’s contiguous coastal waters, including 92% of the Atlantic coast and the entire Gulf coast.5

According to EPA’s Toxic Release Inventory, polluters discharged more than 240.2 million pounds of toxic chemicals into our waterways in 2005 alone.6

In March 2006, the U.S. Geological Survey (USGS) released a report describing the occurrence of pesticides in streams and groundwater over the 10 years spanning 1992-2001. USGS found at least one pesticide in all of the streams studied.7

At least 850 billion gallons of raw sewage are dumped into U.S. waterways every year.8 U.S. sewer systems are aging; without significant investment in wastewater treatment infrastructure, sewage pollution is expected to reach the highest levels in U.S. history by 2025.9

America’s waterways are an important part of our natural heritage, providing us with drinking water and places to swim and fish. Over the last 30 years, we have made significant strides in cleaning up our waterways, but we still have important work to do. Today, many of America’s iconic waterways, from the Great Lakes to the Chesapeake Bay to the Colorado River, are struggling with pollution. The original goals of the Clean Water Act remain unmet benchmarks of water quality in the United States.

Background: A Permit to Pollute

n addition to setting the goals of eliminating the discharge of pollution into America’s waterways and I making all waterways fishable and swimmable, the Clean Water Act embodies four important principles:10

• The discharge of pollutants to navigable waters is not a right.

A discharge permit is required to use public resources for waste disposal and limits the amount of pollutants that may be discharged.

Wastewater must be treated with the best treatment technology economically achievable, regardless of the condition of the receiving water.

Effluent limits must be based on treatment technology performance, but more stringent limits may be imposed if the technology-based limits do not prevent violations of water quality standards in the receiving water.

The National Pollutant Discharge Elimination System

As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program regulates point sources that discharge pollutants into waters of the United States. The Clean Water Act prohibits any facility from discharging pollutants from a point source into a waterway unless it has a NPDES permit. The permit contains limits on what the facility can discharge and monitoring and reporting requirements. The permit provides two levels of control: technology-based limits, based on the ability of dischargers to treat wastewater, and water quality-based limits, if technology-based limits are not enough to protect the water body.11

Pollutants enter waterways from agricultural, domestic, industrial, and other sources. For regulatory purposes, these sources are categorized as either point sources or non-point sources. Point sources refer to discharges that enter waterways from individual pipes or other identifiable locations, such as discharges from sewage treatment plants and industrial facilities. Non-point source pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources and is caused by rainfall or snowmelt that picks up pollutants and deposits them into lakes, rivers, wetlands and coastal waters.

Water pollution may come from both direct and indirect sources. Direct sources discharge wastewater directly into waterways, whereas indirect sources discharge wastewater to a sewage treatment plant, which in turn discharges directly into the receiving water body. NPDES permits are issued only to direct point source dischargers. Indirect dischargers—industrial and commercial facilities that discharge into sewage treatment works—are regulated by the National Pretreatment Program.

The NPDES permitting program is mainly geared toward the regulation of municipal and non-municipal (industrial) direct dischargers. Municipal sources are sewage treatment plants that receive primarily domestic sewage from residential and commercial customers. Larger sewage treatment plants also usually treat wastewater from industrial facilities (indirect dischargers) connected to the sewage system. Many industrial and commercial facilities also discharge into the waterways of the United States. According to

Troubled Waters 4 the U.S. EPA NPDES Permit Writers’ Manual, “at industrial facilities the types of raw materials, production processes, treatment technologies utilized, and pollutants discharged vary widely and are dependent on the type of industry and specific facility characteristics.”12

Roles and Responsibilities of Federal and State Authorities

EPA is authorized under the Clean Water Act to implement and enforce the NPDES program. However, EPA can authorize states that request permission to implement all or part of the NPDES program.

In order for states to receive authorization to implement the NPDES program, they must first establish the necessary legal framework and institutions. This authority is subject to conditions and can be revoked by EPA. States that want to administer the NPDES program submit a letter to EPA from the governor requesting review and approval, a Memorandum of Agreement (MOA), a Program Description, a Statement of Legal Authority (also known as an “Attorney General’s Statement” or “AG Statement”), and the underlying state laws and regulations.

In general, once a state is authorized to administer a part of the NPDES program, EPA no longer conducts these activities. EPA still maintains an oversight role and retains the right to take enforcement action against violators if the state fails to do so. Additionally, EPA retains the right to review each permit issued by the state and may formally object to elements that conflict with federal requirements. If the permitting agency does not address the objection points, EPA will issue the permit directly.

In states without an authorized NPDES program, EPA administers the NPDES program through EPA regional offices, with help from the respective state environmental agencies. Currently, the only states without an approved NPDES program are Alaska, the District of Columbia, Idaho, Massachusetts, New Hampshire, and New Mexico.13 When EPA issues the permit, the Clean Water Act requires that EPA obtain certification from the state where the discharge will occur to ensure that the discharge will be in compliance with effluent limits, the state’s water quality standards, and “any other appropriate requirement of state law.”14

Once a permit is issued through a government agency, the approved state and federal agencies (including EPA) have legal authority to implement and enforce the permit.

Shortcomings of EPA’s Permit Compliance System

The U.S. EPA maintains the Permit Compliance System (PCS) database, which is designed to track permit, compliance and enforcement status data for the NPDES program under the Clean Water Act. Unfortunately, this critical tool that houses information about the nation’s enforcement of the Clean Water Act is outdated and flawed in a few ways, although it remains the best available public data on water quality in the United States.

The PCS database had its last major revision in 1982 and has been identified as an agency weakness publicly since 1999. In a 2003 report, EPA’s Office of the Inspector General stated that the EPA Office of Enforcement and Compliance Assurance “has directed insufficient attention to conducting accurate and timely planning and analysis” for a planned modernization of the PCS database.15 In 2003, the agency, which had promised to modernize the system by the end of the year, admitted that the PCS upgrade would not be complete until September 2006. The Inspector General criticized EPA for allowing the date to slip, noting that without a modernized PCS system, “EPA’s Office of Water cannot effectively manage its Clean Water NPDES program.”16

In mid 2006, EPA moved forward with the PCS modernization by transferring Clean Water Act compliance data from selected states to a new system called the Integrated Compliance Information System-National Pollutant Discharge Elimination System (ICIS-NPDES). ICIS-NPDES will replace PCS as the national database for the NPDES program. Among other changes, the new database is designed to track data currently unavailable in PCS, including data on stormwater, concentrated animal feeding operations and sewer overflows.17 Eighteen states moved from PCS to ICIS-NPDES by August 2006.18 No additional states have moved to ICIS-NPDES as of September 2007. After the 18 states transferred to ICIS-NPDES, compliance data for these states was no longer publicly available on the EPA’s Enforcement and Compliance History Online (ECHO) database. At the end of September 2007, the data for these states was made available to the public on the ECHO database at www.epa.gov/echo.

Available data on water quality in the United States at best paints an incomplete picture of the pollution entering our waterways; at worst, it is a gross underestimate. EPA only requires states to enter data for “major” facilities in its database, covering just a small subset of the universe of facilities. Facilities are designated as “major” based on an EPA scoring system that considers a combination of factors, including toxic pollutant potential, streamflow volume, public health impacts, and proximity to coastal waters. Little compliance information regarding thousands of additional dischargers with NPDES permits is available to the public or in some cases even available at all.19 According to the EPA Inspector General, cost concerns are the reason that EPA does not require states to enter data from “minor” facilities into the system.

Moreover, in the course of completing this report, we identified several areas in which the current PCS database system falls short. EPA informed us that the Oregon data was incomplete. EPA and the states often record discharges in different units—in pounds instead of kilograms, or milligrams instead of micrograms—which can cause unnecessary mathematical errors. Finally, the permit data for facilities is not always up-to-date. EPA and the states should commit to finishing the PCS modernization, keeping the data available to the public and fixing these and other problems as soon as possible.

Findings: America’s Troubled Waterways

ore than two decades after Congress sought to eliminate the discharge of pollution into our M waterways, our analysis of Clean Water Act compliance data finds that facilities across the country continue to discharge more pollution into our waterways than allowed under the law.

In response to a Freedom of Information Act request, EPA provided us with summary data about active major facilitiesb in the Clean Water Act’s National Pollutant Discharge Elimination System (NPDES). The information was generated from the Permit Compliance System (PCS) and covers the time period spanning January 1, 2005 through December 31, 2005. Refer to the methodology section for more details about this data.

Key findings include:

Thousands of facilities continue to exceed their Clean Water Act permits.

Nationally, more than 3600 major facilities (57%) exceeded their Clean Water Act permit limits at least once between January 1, 2005 and December 31, 2005.

These facilities often exceed their permits more than once and for more than one pollutant.

The 10 U.S. states with the most exceedances of Clean Water Act permit limits between January 1, 2005 and December 31, 2005 are Ohio, Pennsylvania, New York, Texas, California, Massachusetts, Louisiana, Tennessee, Alabama, and Florida.

Nationally, 628 major facilities exceeded their Clean Water Act permit limits for at least half of the monthly reporting periods between January 1, 2005 and December 31, 2005.

The Bush Administration’s Assault on the Clean Water Act

s detailed in this report, facilities across the country continue to foul our waterways by discharging more A pollutants than permitted by law. At a time when federal officials should be working with the states to improve water quality and enforce the Clean Water Act, the Bush administration has suggested, proposed, or enacted numerous policies that would weaken the Clean Water Act and threaten the future of America’s rivers, lakes, streams and coastal waters.

Allowing More Pollution in Waterways

The Bush administration has enacted two separate policies that eliminate longstanding Clean Water Act protections for waterways across the country. In January 2003, the Bush administration issued a policy guidance that instructed U.S. EPA and U.S. Army Corps of Engineers staff to stop implementing Clean Water Act protections for small streams, wetlands, ponds and other waters.20 In June 2007, the Bush administration announced a second policy guidance that further weakens Clean Water Act safeguards for many streams and wetlands and adds confusion to which waters are protected.21 The streams, wetlands and other waterways at risk from these two policies are the source waters for America’s rivers, lakes and bays. These smaller waterways filter pollution, sustain water supplies, control flood waters and provide habitat for fish and other wildlife.22 Harm to the source waters affects the larger waterways downstream.23

The 2003 and 2007 policy directives put thousands of miles of streams and millions of acres of wetlands in danger of unlimited pollution and development. EPA has acknowledged that the 2003 policy alone could remove federal Clean Water Act protections from 20 million acres of wetlands, or about 20% of the wetlands in the lower 48 states.24 When the federal government decides a waterway is outside of the scope of the Clean Water Act, all protections of the law are removed, including the need for a NDPES permit to discharge pollution into that waterway. More than 40% of the NPDES permitted facilities, for which EPA has location data, discharge into headwater, intermittent or ephemeral streams.25 These are the categories of streams that are at risk of losing Clean Water Act protection.

As a result of these policies, developers, mining companies and other polluters seeking exemption from the Clean Water Act are able to argue that wetlands, streams, ponds or other waters fall outside of the Clean Water Act’s jurisdiction. The Army Corps’ own reporting shows that thousands of waters across the country have already lost protection as a result of the 2003 policy.26 Waters that have lost protection include a 150- mile-long river basin in New Mexico, four thousand acres of wetlands in Florida, and a 69-mile-long canal used as a drinking water supply in California.27

Threatening Public Health

Sewage contains bacteria, viruses, parasites, intestinal worms, and a host of other organisms that cause beach closings, kill fish and harm public health. Sewage-contaminated waters can cause illness ranging from nausea and diarrhea to cholera, dysentery, infectious hepatitis, and severe gastroenteritis.28 Despite these public health and environmental threats, the Bush administration has taken actions that actually increase the amount of sewage pollution into U.S. waterways.

Troubled Waters 14 Sewage “Blending” In November 2003, the Bush administration issued a draft policy guidance that weakened restrictions on sewage treatment facilities for discharging inadequately treated sewage into waterways when it rains.29 The proposal would allow sewage treatment facilities to divert sewage around secondary treatment units and then combine the filtered but untreated sewage with fully treated wastewater before discharging it into waterways in a process called “blending.” The effect of this sewage blending would be to remove the crucial second step in the process of sewage treatment during wet weather, specifically the biological treatment of the sewage. Because the biological treatment removes most of the pathogens, blended sewage has significantly higher levels of pollutants than sewage that has undergone full treatment.30

The Bush administration withdrew the policy on May 19, 2005, just hours before the U.S. House of Representatives voted to block EPA from finalizing it. In December 2005, EPA proposed a second sewage blending policy that has not yet been finalized.31

Sewer Overflows In January 2001, EPA proposed to clarify and expand permit requirements for 19,000 municipal sanitary sewer collection systems in order to reduce sewer overflows. When sanitary sewers are overloaded, inadequately maintained or obstructed, they often overflow, dumping raw and inadequately treated sewage into basements, streets, and waterways. EPA estimates that at least 40,000 sanitary sewer overflows occur nationally each year.32

The proposed Sanitary Sewer Overflow Rule, the product of a federal advisory committee that met for five years, would help communities improve some sanitary sewer systems by requiring facilities to develop and implement new capacity, management, operations, maintenance, and public notification programs.33 This rule would, among other things, require sewer operators to monitor sewers and notify health authorities and the public when overflows could potentially harm public health. The Bush administration has blocked these regulations ever since it took office.

Undercutting Enforcement and Protection

Budget cutbacks threaten EPA’s abilities to effectively police polluters and protect the nation’s waters. From 1997 to 2006, EPA’s total budget has declined 13 percent, when adjusted for inflation.34 The Bush administration continued this trend with its fiscal year 2008 budget proposal. The administration’s proposed budget would cut funding for EPA by more than $400 million. The most significant cuts -$395 million- are to the Clean Water State Revolving Fund, which provides low interest loans to communities to upgrade wastewater treatment systems and supports other water infrastructure projects.

The continued cuts to EPA’s budget prevent the agency from putting enough environmental cops on the beat and limit the number of inspections to detect violations of the Clean Water Act, Clean Air Act and other key environmental laws. During the last 10 years, EPA funding for enforcement has declined. According to a report by the Government Accountability Office, between 1997 and 2006, EPA’s total enforcement funding decreased five percent when adjusted for inflation, with an eight percent reduction in funding for the regional offices that shoulder a significant responsibility for enforcement. 35 As a result of the funding cuts, the number of regional enforcement staff was reduced by about five percent. In addition, the GAO found that EPA’s grants to states to implement and enforce environmental programs decreased by nine percent in real terms with a 22 percent decline between fiscal years 2004 and 2006.

Troubled Waters 15 The Bush administration’s poor track record on environmental enforcement is well-documented. In 2007, the EPA Office of Inspector General reviewed 56 major facilities in long-term significant non-compliance with Clean Water Act NPDES permits between July 2002 and June 2005.36 The Inspector General found that EPA and states did not take suitable enforcement actions to address all of the violations at 21 of the facilities and took no enforcement actions at eight of the facilities. At 35 of the facilities reviewed, none of the enforcement actions that the Inspector General’s office could assess were taken in a timely manner, leading facilities to continue to violate their permits for extended periods of time.

A December 2003 Knight Ridder analysis of 15 years of environmental enforcement records found that the Bush administration in its first three years caught and punished far fewer polluters than the two previous administrations.37 Knight Ridder examined EPA data in 17 categories and subcategories of civil enforcement since January 1989 and compared the records of the past three administrations. In 13 of those 17 categories, the George W. Bush administration had lower average numbers than the Clinton administration. And in 11 of those categories, the 2003 average was lower than the 2001 average, showing the trend worsening over time. The monthly average of violation notices against polluters, a critical enforcement tool, dropped 58 percent compared with the Clinton administration’s monthly average; notices of water pollution violations were down 74 percent.

A September 2007 Washington Post analysis of EPA and U.S Department of Justice data found that between fiscal years 2002 and 2006, the number of Bush administration civil lawsuits filed against polluters who refuse to settle dropped almost 70 percent compared with a four-year period in the late 1990s.38 New investigations, prosecutions and convictions all decreased by more than a third. In addition, the Washington Post found that the current number of investigators in EPA’s Criminal Investigation Division has fallen below the minimum number required by the 1990 Pollution Prosecution Act.

Other Rollbacks to the Clean Water Act

The Bush administration has proposed or enacted numerous other policies that chip away at Clean Water Act protections, including:

In August 2007, the Bush administration proposed removing a Reagan-era rule known as the “buffer zone rule” that prohibits coal-mining activities from disrupting areas within 100 feet of streams.39

In March 2007, the Bush administration expanded the number of Clean Water Act “nationwide permits” – five year general permits that allow the filling of wetlands and streams but do not receive the same level of environmental scrutiny as individual permits and provide no public notice or comment opportunity.40

In November 2006, the Bush administration finalized a rule to exclude pesticide applications from regulation under the Clean Water Act’s NPDES program and allow pesticides to be discharged into rivers, lakes, streams, and other waters without a permit.41

In June 2006, the Bush administration proposed a rule to allow water polluted with toxic chemicals, sewage or other contaminants to be transferred from one waterway into another without a NPDES permit.42

In June 2006, the Bush administration issued a final rule exempting sediment runoff at oil and gas construction sites from regulation under the Clean Water Act.43

Recommendations

hirty-five years after passage of the Clean Water Act, the law’s most basic promises remain unfulfilled. T We need to tighten enforcement of the law and strengthen the Act’s fundamental principles. Unless we punish polluters that exceed their permits and reduce the amount of pollution facilities can discharge legally, we will never realize the Clean Water Act’s vision of waters free of toxic pollutants and safe enough for fishing and swimming.

Reverse Policies that Weaken the Clean Water Act

As detailed above, the Bush administration has suggested, formally proposed or enacted policies designed to limit the Clean Water Act in scope and in strength. Three decades after the birth of this landmark legislation, more than 300,000 miles of rivers and shoreline and five million acres of lakes remain too contaminated for recreational use.44 Rather than weakening the Clean Water Act, the Bush administration should:

Withdraw the January 2003 and June 2007 policy directives that eliminate Clean Water Act protections for many small streams, wetlands and other waters.

Fund EPA at the levels necessary to hire adequate environmental enforcement staff and enforce the Clean Water Act.

Fully fund the EPA’s Clean Water State Revolving Fund to help communities improve their wastewater treatment systems.

Direct EPA to ensure that all sewage is properly treated, implement the proposed rule to regulate sanitary sewer overflows, and improve public notification of overflows that threaten human health.

Withdraw all proposed rules and reverse finalized rules to exempt certain industries and activities from the Clean Water Act.

Strengthen Implementation and Enforcement of the Clean Water Act

The Bush administration and state officials should improve implementation and tighten enforcement of the Clean Water Act to help reach the goal of pollution-free waters.

Prevent Facilities from Profiting from Pollution

The existing Clean Water Act allows “economic benefits” to be taken into consideration when assessing penalties. Unfortunately, EPA has acknowledged that penalties rarely recover the profits companies gain from their non-compliance. In other words, under current Clean Water Act enforcement practices, it often pays to pollute illegally, which creates incentives to break the law, allows states and violators to cut sweetheart deals, and places those who comply with the law at a competitive disadvantage. Courts and administrative hearing officers should assess a penalty that exceeds the amount of economic benefit

Troubled Waters 17 gained by the polluter as the result of its non-compliance. In addition, any state with an authorized Clean Water Act program should collect and make public all fines levied against and collected from polluters.

Tighten Pollution Limits

With the Clean Water Act, Congress intended to eliminate water pollution through a gradual tightening of permits based on emerging control technologies. The Act’s authors envisioned progressive permit tightening, coupled with enforcement actions against permit violators, to eventually reduce industrial and municipal pollution levels and achieve the interim Clean Water Act goal of fishable and swimmable waterways and ultimately zero discharge.

Progressive permit tightening, however, has not occurred consistently. By failing to regularly reevaluate permit limits and lower allowable pollution levels based on advances in technology, the government is missing a fundamental opportunity to reduce and eliminate pollution.

Revoke Permits from Repeat Violators

Under the principles of the Clean Water Act, EPA and state agencies are not issuing facilities permits to pollute indefinitely, but are granting them a temporary right to discharge pollution into waterways while they reduce and eventually eliminate their waste stream. This temporary right must not be taken for granted. EPA and state agencies should deny permit issuance or renewal to applicants whose compliance history shows a repeated pattern of significant noncompliance with the Clean Water Act.

Implement Pollution Prevention Initiatives

Pollution prevention means reducing the use of chemical inputs in order to generate less toxic waste, rather than relying on end-of-pipe pollution control technologies to stop waste chemicals from entering water discharges. Pollution prevention tends to be more effective in cutting use of chemicals and often saves facilities money otherwise spent handling hazardous materials.

Each applicant for a permit to discharge one or more pollutants should be required to submit, with the application for the permit, a pollution prevention plan that details the applicant’s plans for reducing and eliminating the use and discharge of such pollutants at a measurable rate.

Remove Current Obstacles to Citizen Suits

Citizens should be allowed to sue for past violations of the Clean Water Act, similar to the 1990 amendments to the Clean Air Act. Furthermore, inadequate government enforcement actions should not preclude citizen suits. Only judicial or enforcement actions that recoup the full economic benefit gained by violating the law should preclude subsequent citizen enforcement.

Troubled Waters 18 Expand the Public’s Right to Know

Access to accurate and consistent reporting is fundamental to the success of the Clean Water Act’s permitting and enforcement programs. Without it, protection of our waterways is impossible. The Bush administration and state agencies should increase the public’s right to know about water pollution.

EPA should complete the modernization of the Permit Compliance System as soon as possible to ensure that permit and enforcement data on all major facilities (at minimum) in each state are accurate, up- to-date and comprehensive.

EPA and the states should compile and make public an analysis of enforcement actions taken during the preceding year, including the number of enforcement actions; the type of enforcement actions; the average penalty assessed and collected for each action; the total number of facilities in noncompliance and the reason for such noncompliance; and the number and percentage of facilities with expired permits.

EPA should maintain and expand the Toxics Release Inventory (TRI) program. Since 1987, TRI has ensured the public’s right-to-know about toxic chemicals in communities by requiring companies to disclose the pollution they release to the water, air and land. EPA should reverse its recent rule that reduced the quantity and quality of toxic chemical data submitted under TRI and available to the public.45 Instead, EPA should look for ways to expand TRI.

EPA should expand the public’s right to know to include information on chemical use. While TRI discloses facilities’ direct discharges of chemical pollution every year, little public information exists about chemicals used in workplaces and placed in products. In order to move toward the Clean Water Act’s goal of zero-discharge, industrial facilities need to practice pollution prevention—reducing the use of chemicals at the source—rather than relying on pollution control technologies to limit releases once waste has been generated. Requiring companies to disclose their chemical use gives them an incentive to reduce use. In Massachusetts, where chemical-use reporting is required in combination with pollution prevention planning, companies decreased their toxic chemical use by 41% between 1990 and 2004. These companies are generating 65% less byproducts or waste per unit of product and have reduced releases of certain on-site chemicals by 91%.46

EPA should maintain and expand the Enforcement and Compliance History Online (ECHO) database. The ECHO database provides the public with access to important information about facilities’ compliance with the Clean Water Act, Clean Air Act, and Resource Conservation and Recovery Act. EPA should continue to expand the information provided to the public on this site and deny any requests by the regulated industries to remove any information from the public domain.

Methodology

1. Obtaining the data. To obtain the data, we submitted a Freedom of Information Act (FOIA) request in January 2007, to which EPA responded in February 2007.

2. Scope and source of the data. The data provided through the FOIA request contains summary data about active major facilities in the Clean Water Act’s National Pollutant Discharge Elimination System. All information was generated from the Permit Compliance System (PCS). The data covers the time period spanning January 1, 2005 through December 31, 2005.

3. Ensuring accuracy of the data. After receiving the data from EPA, we contacted each state agency— except in states where EPA administers the NPDES program—and offered them an opportunity to review the data for accuracy. The following states (in addition to the states where EPA administers the Clean Water Act) did not review any of the water quality data, due to resource limitations or failure to respond to repeated requests: Arkansas, Delaware, Iowa, Indiana, Louisiana, Pennsylvania, Tennessee, and Washington.

In addition to making the corrections noted by the state agencies, we deleted or updated the following records from the database provided by EPA:

- We deleted all exceedances greater than 10,000% as likely data entry errors, except for parameters such as fecal coliform and e.coli.

- In certain instances, PCS parameter-level effluent violations will show the value 99999% over limit. This value is a code indicating that PCS was not able to properly interpret the measurement that was submitted by the permittee. Therefore, 99999% values are not necessarily violations; as such, we excluded these 99999% values from our analysis, except as noted below.

- Some facilities reported discharges of “<“ or “>“ a given value. EPA’s PCS database drops the “<“ and “>“ symbols and calculates the violation as the base number; in most cases, we were unable to verify whether the PCS database correctly calculated the percentage over the effluent permit limit. We eliminated all records for which states reported discharges using a character such as “<“ or “>“, except when the facility reported a discharge of “>“ a given value that was higher than the permitted limit or “<” a given value that was lower than the permitted limit for concentration minimum. We coded these records, which often show a 99999% value, as an “apparent exceedance of undetermined magnitude.”

- Some facilities hold permits for parameters that do not set specific discharge limits but instead are PASS/FAIL or YES/NO. For many of these, EPA valued the exceedances at 99999%. We counted any violation of a PASS/FAIL or YES/NO permit parameter as a 100% exceedance.

4. Data limitations. The data covers major facilities only. Facilities are designated as “major” based on an EPA scoring system that considers a combination of factors, including toxic pollutant potential, streamflow volume, public health impacts, and proximity to coastal waters. For example, a major municipal facility is a publicly owned treatment works that serves a population of 10,000 or more, discharges one million gallons or more of wastewater daily, or has a significant impact on water quality. Because we only

Troubled Waters 20 looked at major facilities, this report examines a small subset of the total number of facilities discharging pollutants into U.S. waters.

5. Oregon data. EPA did not provide data for Oregon facilities as Oregon has not entered data in PCS since August 31, 2004. As such, we excluded Oregon from the report’s analysis. EPA is working with Oregon to update the data in PCS.

6. Definition of “exceedance.” We count any exceedance (greater than 0% above the permit limit or greater than 0% below a minimum permit limit) for any given parameter during any given reporting period as an exceedance. If a facility exceeded its permit level for a given parameter for daily maximum and monthly average, we count this as two exceedances but as one facility in exceedance.

7. Definition of an “apparent exceedance of undetermined magnitude.” In some cases, facilities report a discharge of “>“ or “<” a given value. When this value was higher than the permitted limit, or lower than a minimum permit limit, we coded each of these records as an “apparent exceedance of undetermined magnitude.” For parameters such as fecal coliform, some facilities reported “T”, which means “too many to count.” We also categorized each of these instances as an “apparent exceedance of undetermined magnitude.”

8. Calculating the average permit violation by state. To calculate the average exceedance (measured as the percent variation from the permit limit), we averaged all of the exceedances in a state, excluding non-violations, fields displaying EPA’s 99999% code and additional records we coded as “apparent exceedance of undetermined magnitude.”

9. Number of major facilities by state. Data for the number of major facilities in each state, which forms the basis of the calculations in Table 1, were obtained by searching by state for all major facilities at http://www.epa.gov/echo/compliance_report_water.html and from information provided by EPA and state environmental agency staff.
